Lipoprotein(a) induces glomerular superoxide anion production.
BACKGROUND Lipoprotein(a) (Lp(a)) is considered to accelerate glomerular injury in various forms of renal disease. Several tissue culture studies suggested that biological effects of Lp(a) are inhibitable by oxygen radical scavengers. Since reactive oxygen metabolites (ROM) are important mediators of renal disease, we studied the effects of native and oxidized Lp(a) on generation of the ROM sup...
متن کاملNeutrophil Superoxide Anion Production
Superoxide and other oxygen radicals produced by activated polymorphonuclear leukocytes (PMN) may be important causes of tissue damage in a number ofinflammatory conditions. Therefore, a drug which suppresses PMN responses in vivo is potentially important. In vitro, pentoxifylline (PTOX) inhibits superoxide anion production when PMN are stimulated with an activated complement component (C5a Des...
متن کاملHypercholesterolemia increases endothelial superoxide anion production.
Indirect evidence suggests accelerated degradation of endothelium-derived nitric oxide (ENDO) by superoxide anion (O2-) in hypercholesterolemic vessels (HV). To directly measure O2- production by normal vessels (NV) and HV, we used an assay for O2- based on the chemiluminescence (CL) of lucigenin (L). HV (1 mo cholesterol-fed rabbits) produced threefold more O2- than NV (1.47 +/- 0.20 nM/mg tis...
متن کاملDiacylglycerol accumulation and superoxide anion production in stimulated human neutrophils.
Exogenous diacylglycerols stimulate neutrophil superoxide anion production, suggesting that endogenous diacylglycerols may function as second messengers for this biological response. We have measured the diacylglycerol mass in human neutrophils stimulated by fMet-Leu-Phe, ionomycin, and concanavalin A and have correlated the kinetics and magnitude of the diacylglycerol response with those for s...
متن کاملCollagen activates superoxide anion production by human polymorphonuclear neutrophils.
Human polymorphonuclear neutrophils (PMNs), purified on Ficoll-Hypaque cushions, were incubated for 5 min with calf skin acid-soluble collagen and the released superoxide anions (O2-) measured spectrophotometrically by reduction of ferricytochrome c or by chemiluminescence analysis. This collagen stimulated the release of O2- unless it had been treated with pepsin. The stimulatory activity rema...
